A lightweight, production-ready Model Context Protocol (MCP) server built with .NET 9, running as a Windows Service. Connect your AI assistant to your local machine — read system stats, monitor processes, scan your network, check the weather, and more.
Built by two curious minds who don't follow rules. 🚀
